Secretary of Defense James Mattis has called on North Korea to stop considering “actions that will lead to the end of the regime.”

“The DPRK must choose to stop isolating itself and stand down its pursuit of nuclear weapons,” he said in a statement. “The DPRK should cease any consideration of actions that would lead to the end of its regime and the destruction of its people.”

He added: “The DPRK regime’s actions will continue to be grossly overmatched by ours and would lose any arms race or conflict it initiates.”
